FOOT-POWER.

BPECIFICATION forming part of Letters Patent No. 298,566, dated May 13,1884.

Application filed February 21, 1884.

To aZZ whom. it may concern.-

Be it known that I, HENRY FIELD, J r., of New Bedford, in the county ofBristol and State of Massachusetts, have invented a new and ImprovedFoot-Power, of which the 'following is a full, clear, and exactdescription.

The object of my invention is to provide a new and improved foot-powerto be used in place of the usual treadle-erank and connect ing-rod foroperating machinery by foot.

The invention consists of the combinations of parts and theirconstruction, substantially as hereinafter fully set forth, and pointedout in the claims.

Reference is to be had to the accompanying drawings, forming part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 is a side view of my improved footpower. Fig. 2 is a sectionalelevation of the same on the line a: m, Fig. 1. Fig. 3 is a detail sideview of the elbow-lover, the pintles being shown in section.

The standard A, united by top rods, A, and a bottom central shaft orrod, 13, form a frame. A foot-plate, G, is pivoted centrally to rock onand above the shaft or rod 13, and its ends are pressed upward by spiralsprings D, held between the under side of the foot-plate O and the uppersurface of a cross-bar, E, held on and below the shaft 13 by means of abindingscrew, a, which permits of adjusting the bar E so as to beinclined more or less, according to the inclination of the foot-plate inits normal position. A11 upwardly-projecting bar, F, is loosely mountedat its lower end on the shaft B, and has a fork, F, formed on its upperend, from the outer edge of each prong of which fork apertured lugs oreyes (I 9 project, through which rods G pass, which project downwardfrom the bottom of a curved longitudinal frame, I, in the opening ofwhich a friction-wheel, H, is located, and mounted on the driving-shaftJ, on which shaft a belt-pulley, K, or a combined belt-pulley andflywheel, is mounted. The wheel H is provided with a rubber rim, H. Thediameter of the wheel H, including its rim H, is slightly less than thewidth of the opening in the frame I. Spiral springs L, surrounding therods G, are

i held between the bottom lugs, 51, and nuts M, screwed on the rods, andpress the frame I upward. The frame I is provided at the center of itsbottom bar with a downwardly-projecting arm, IT, on the lower end ofwhich the angle-pivot h of an elbow-lever, O, is held, the end of theupper arm of the said lever 0 being pivoted to one of the prongs of thefork F. The downward-projecting arm of the lever 0 is provided with alongitudinal slot, P, through which a pintle, Q, passes, which alsopasses through a longitudinal slot, R, formed in a standard, S, of thefoot-plate G, the said pintle being provided with a nut, T, for lockingit in place. The springs 0 press up the ends of the foot-plate O, andbring the same back to the normal position. The pressure of the rim ofthe wheel H can be regulated by adjusting the pintle Q higher or lower.

The operation is as follows: If the lower end of the foot-plate Gthatis, the end toward the operator-is depressed, the swinging part of thedevice is moved in the direction of the arrow a, and the standard S,which is independent of the arm F, swings the lower, end of theelbow-lever O slightly in the direction of the arrow a, thereby movingthe anglepivot lb of the angle-lever O upward, thereby raising the frameI and bringing the contact with the rim of the wheel H, which is thusrevolved by friction in the direction of the arrow 1). If the oppositeor inner end of the foot-plate G is depressed, the swinging part of thedevice is moved in the inverse direction of the arrow a, and the upperend of the standard S moves the lower end of the anglelevcr O in theinverse direction of the arrow a, thereby moving the angle-pivot h ofthe angle-lever O and the frame I, connected therewith, downward, andbringing the bottom of the top bar of the frame I in contact with therim of the wheel H, thus revolving the wheel H in the direction of thearrow 1). If the angle-lever O is pivoted to the other prong of the forkF, the motion is reversed.

claim as new, and desire to secure by Letters Patent, is

1. The combination, with a pulley or wheel,

inner edge of the bottom bar of the same in' Having thus described myinvention, what I IOO of a rocking frame surrounding it, an elbowleverconnected with the frame, and with a rocking standard, and of a rockingarm for holding the frame surrounding the wheel, substantially as hereinshown and described.

2. The combination, with a pulley or wheel, of a rocking framesurrounding it, a rocking arm on which the frame is held in such amanner that it can have a slight vertical movement, and an elbow-leverpivoted to the frame, to the arm holding the frame, and to a rockingstandard, substantially as herein shown and described.

3. The combination, with the wheel H, of the rocking frame I,surrounding it, and provid ed with downward]y-projecting rods G, therocking arm F on the shaft B. the fork F, formed on the upper end of thearm F, in the prongs of which fork the rods G are held, the standard Son the rocking foot-plate G, and of the angle-lever O, pivoted to thelower end of an arm, N, vof the frame I, to the fork F, and to thestandard S, substantially as herein shown and described.

4 The combination, with the wheel H, of 25 the frame I, having thedownwardly-projecting rods G, and the arm N, the rocking arm F on theshaft B, the fork F on the upper end of the arm F, the springs L, thenuts M on the rods G, the angle-lever O, and the standard S on a rockingfoot-plate, substantially as herein shown and described.

5. The combination, with the rocking footplate 0, of the cross-bar E,held on the shaft B and below the plate 0, and of the springs D,interposed between the foot-plate G and the bar E, substantially asherein shown and described.
